7. Jamal is rolling along on his 4.0 kg skateboard with a constant speed of 3.0 m/s when he
jumps off the back and continues forward with a velocity of 2.0 m/s relative to the ground. This
causes the skateboard to go flying forward with a speed of 15.5 m/s relative to the ground.
What is Jamal's mass?

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
